Description

本発明は、形鋼のフランジ等の造営材に固定され、吊りボルト、照明器具、配線器具、配管材等の配設体を支持する造営材への固定具に関するものである。 The present invention relates to a fixture for a construction material that is fixed to a construction material such as a flange of a shape steel and supports an arrangement body such as a suspension bolt, a lighting device, a wiring device, and a piping material.

従来より、前記吊りボルト、照明器具等の配設体は固定具を使用して形鋼のフランジ等の造営材に取付けられている。この種の固定具に関しては、例えば、実用新案登録第３１２１５８１号公報に記載のものが知られている。図１３は前記公報に記載された造営材への固定具を示し、図１３において、固定具８１は、Ｈ形状の形鋼６１のフランジ６２の一方に取付けられる側面視略コ字状の吊り金具８２に、吊りボルト７２等の配設体を支持する支持部材８３が連結ボルト４２を介して取付けられているとともに、吊り金具８２の取付固定を補強する補強金具８４が取付けられている。前記吊り金具８２は、側面視略コ字状に形成された金具本体８５の挿入開口８５ａから内部空間８５ｂに形鋼６１のフランジ６２を挿入し、これを金具本体８５と固定ボルト３２とで挟持することにより、形鋼６１のフランジ６２に固定されるようになっている。吊りボルト７２は、支持部材８３の底板８３ａの挿通孔に挿通された後、底板８３ａに上下一対のナット８６，８６が締付け固定されることにより支持される。一方、補強金具８４は、形鋼６１のフランジ６２に引掛かるく字板状の掛止板８４ａと、この掛止板８４ａに設けられている透孔に一端が挿通するとともに他端が吊り金具８２内を貫通して吊り金具８２の後端から突出するネジ棒８４ｂと、このネジ棒８４ｂの一端に螺合して掛止板８４ａを背面から位置固定するナット８４ｃと、吊り金具８２の後端に当接するとともにネジ棒８４ｂの他端が挿通されるコ字板状の固定板８４ｄと、ネジ棒８４ｂの他端に螺合して固定板８４ｄを位置固定するナット８４ｅとで構成されている。 2. Description of the Related Art Conventionally, an arrangement body such as a suspension bolt and a lighting fixture is attached to a construction material such as a flange of a shape steel using a fixture. As this type of fixture, for example, the one described in Utility Model Registration No. 3121581 is known. FIG. 13 shows a fixture for a construction material described in the above publication. In FIG. 13, a fixture 81 is a substantially U-shaped hanging bracket attached to one of flanges 62 of an H-shaped section 61. A support member 83 that supports an arrangement body such as a suspension bolt 72 is attached to 82 through a connection bolt 42, and a reinforcement fitting 84 that reinforces the fixing of the suspension fitting 82 is attached. In the suspension fitting 82, a flange 62 of the shape steel 61 is inserted into the internal space 85b from the insertion opening 85a of the fitting main body 85 formed in a substantially U shape when viewed from the side, and is sandwiched between the fitting main body 85 and the fixing bolt 32. By doing so, it is fixed to the flange 62 of the section steel 61. The suspension bolt 72 is supported by a pair of upper and lower nuts 86, 86 being fastened and fixed to the bottom plate 83a after being inserted into the insertion hole of the bottom plate 83a of the support member 83. On the other hand, the reinforcing metal fitting 84 has a rectangular plate-like hooking plate 84a hooked on the flange 62 of the shaped steel 61, and one end inserted into a through-hole provided in the hooking plate 84a and the other end is a hanging metal fitting 82. A threaded rod 84b penetrating from the rear end of the suspension fitting 82, a nut 84c screwed to one end of the threaded rod 84b to fix the retaining plate 84a from the back, and a rear end of the suspension fitting 82 The U-shaped fixing plate 84d is inserted into the other end of the screw rod 84b and the nut 84e is screwed into the other end of the screw rod 84b to fix the fixing plate 84d. .

固定具８１は上記のように構成されているので、種々のサイズのフランジを有する形鋼に対応して固定することができるとともに、ネジ棒８４ｂの両端に螺合するナット８４ｃ、ナット８４ｅにより両方向からの緊締具合の調整が可能であるため、調整範囲が広く、また、掛止板８４ａが形鋼６１のフランジ６２に線接触するためにぐらつきの生じ難い安定した固定が可能である。
実用新案登録第３１２１５８１号公報 Since the fixture 81 is configured as described above, the fixture 81 can be fixed in correspondence with the shape steel having flanges of various sizes, and in both directions by the nut 84c and the nut 84e screwed to both ends of the screw rod 84b. Since the tightening degree can be adjusted, the adjustment range is wide, and the latching plate 84a is in line contact with the flange 62 of the shaped steel 61, so that it can be stably fixed with little wobbling.
Utility Model Registration No. 3121581

しかし、前記公報に記載の固定具は、ネジ棒８４ｂの両端にナット８４ｃ、ナット８４ｅが螺合しており、例えばネジ棒８４ｂのいずれか一端側からナットを締付ける際には、他端側のナットがから回りしないよう、締付中、ネジ棒８４ｂの他端側に手を伸ばして他端側のナットを保持していなければならない。
そこで、例えば一端側の掛止板８４ａにナット８４ｃの回り止め機構を設け、他端側の固定板８４ｄに位置固定されているナット８４ｅのみを締付けるために回動を許容する構成とすることが考えられる。この場合は、他端側のみの操作でナット８４ｅを締付け固定することができる。 However, in the fixture described in the above publication, a nut 84c and a nut 84e are screwed to both ends of the screw rod 84b. For example, when the nut is tightened from one end side of the screw rod 84b, In order to prevent the nut from rotating, it is necessary to reach to the other end of the screw rod 84b and hold the nut on the other end during tightening.
For this reason, for example, a locking mechanism for the nut 84c is provided on the latch plate 84a on one end side, and the rotation is permitted to tighten only the nut 84e that is fixed to the fixing plate 84d on the other end side. Conceivable. In this case, the nut 84e can be fastened and fixed only by the operation on the other end side.

ところが、その一方、一端側の掛止板８４ａにナット８４ｃの回り止め機構を設けると、ネジ棒８４ｂの他端側からしかナット８４ｅの締付作業を行なうことができず、作業方向が制約されるため、仮に他端側に障害物等がある場合には、反対の一端側からナット８４ｃの締付作業を行なうことができなくなる。このため、障害物等のある他端側の狭いスペース内での窮屈な締付作業を強いられることとなるから、作業性は低下する。 However, if a locking mechanism for the nut 84c is provided on the latch plate 84a on one end side, the nut 84e can be tightened only from the other end side of the screw rod 84b, and the working direction is restricted. Therefore, if there is an obstacle on the other end side, the nut 84c cannot be tightened from the opposite end side. For this reason, since the tightening operation | work in the narrow space of the other end side with an obstruction etc. will be forced, workability | operativity will fall.

そこで、ネジ棒８４ｂの左右いずれの方向からでも締付作業を行なうことができ、かつ、締付中、反対側のナットを保持することなく締付けできるように、掛止板８４ａ及び固定板８４ｄのそれぞれに、回り止め機構を有するものと有しないものとの２種類を用意し、現場においていずれかを選択し、使用することが考えられる。
しかし、その場合は、部品点数が増えることになるから、部品コストが上昇し、取り扱いが煩雑化し、保管、運搬等における部品管理も煩わしいものとなる。また、回り止め機構有り無しの挟持板を間違えてネジ棒に取付けた場合は、これを取り外し、再度装着し直さなければならないという不都合も生ずる。 Therefore, the fastening plate 84a and the fixing plate 84d can be tightened from either the left or right direction of the screw rod 84b and can be tightened without holding the nut on the opposite side during tightening. It is conceivable to prepare two types, one having a detent mechanism and one not having a detent mechanism, and selecting and using one at the site.
However, in that case, the number of parts increases, so the part cost increases, handling becomes complicated, and parts management in storage, transportation, etc. becomes troublesome. In addition, if the clamping plate with or without the rotation prevention mechanism is mistakenly attached to the screw rod, there is a disadvantage that it must be removed and remounted.

そこで、本発明は、ナット等の締付具を介して一対の挟持体で造営材を挟持して固定するものにおいて、１種類の一対の挟持体で、反対側の締付具を保持することなく、かつ、いずれの方向からでも締付作業を行なうことのできる造営材への固定具の提供を課題とするものである。 Therefore, in the present invention, in which the construction material is clamped and fixed by a pair of clamping bodies via a clamping tool such as a nut, the clamping tool on the opposite side is held by one type of clamping body. It is an object to provide a fixture for a construction material that can be tightened from any direction.

請求項１の造営材への固定具は、造営材を挟持することにより該造営材に固定されるものであって、前記造営材を挟持する一対の挟持体と、外面に雄ねじを備えた棒状体と、該棒状体に螺合して前記挟持体を挟圧するナットとを備えている。そして、前記挟持体は、前記棒状体が貫通する貫通部を備えるとともに、該貫通部を貫通した前記棒状体に螺合した前記ナットまたはボルト体の頭部に係合する係合部を備え、前記係合部は、ワッシャーが介在することにより、前記ナットまたは前記ボルト体の頭部が係合することなく回動可能に形成されている。
そして、棒状体が一対の挟持体を貫通した状態で、いずれか一方の挟持体を貫通した棒状体に螺合したナットまたはボルト体の頭部は前記一方の挟持体の係合部に係合し、いずれか他方の挟持体を貫通した棒状体に螺合したナットまたはボルト体の頭部は前記他方の挟持体の係合部との間に前記ワッシャーが介在している。
この固定具は直状の棒状体を使用してＨ形状の形鋼等の造営材に固定される態様のものである。

以下、本発明の実施形態の造営材への固定具１を図１乃至図８に基づいて説明する。なお、本実施形態では、固定具１を固定する造営材としてＨ形状の形鋼を例示する。
図１乃至図３において、固定具１は、造営材である建物の天井等に設けられたＨ形状の形鋼６１のフランジ６２に固定されて配設体を支持するものであり、造営材を相対向する側から挟持する左右一対の挟持体と、外面に雄ねじを備えた棒状体２と、各挟持体の外側から棒状体２に螺合する第１ナット３及び第２ナット４とを備えている。そして、各挟持体は、前記棒状体２が貫通する貫通部を備えるとともに、この貫通部を貫通した棒状体２に螺合したナットに係合する係合部を備える。この係合部は、ワッシャー５が介在することにより、ナットが係合することなく回動可能に形成されている。第１ナット３及び第２ナット４は六角ナットで形成されている。以下、各構成部材について詳細に説明する。 Hereinafter, a fixture 1 for a construction material according to an embodiment of the present invention will be described with reference to FIGS. 1 to 8. In this embodiment, an H-shaped steel is exemplified as a construction material for fixing the fixture 1.
1 to 3, the fixture 1 is fixed to a flange 62 of an H-shaped steel plate 61 provided on a ceiling or the like of a building which is a construction material, and supports the arrangement body. A pair of left and right sandwiching bodies sandwiched from opposite sides, a rod-like body 2 having an external thread on the outer surface, and a first nut 3 and a second nut 4 that are screwed into the rod-like body 2 from the outside of each sandwiching body are provided. ing. And each clamping body is provided with the engaging part engaged with the nut screwed by the rod-shaped body 2 which penetrated this penetration part while it has the penetration part which the said rod-shaped body 2 penetrates. The engaging portion is formed so as to be rotatable without being engaged with the nut by interposing the washer 5. The first nut 3 and the second nut 4 are formed of hexagon nuts. Hereinafter, each component will be described in detail.

まず、前記棒状体２は、全長に至って外面に雄ねじを備えた直状のボルト体で形成されており、全長は少なくとも形鋼６１の左右両側のフランジ６２全体の幅寸法より長く形成され、形鋼６１のフランジ６２の下面側に配設される。 First, the rod-like body 2 is formed of a straight bolt body having an external thread extending to the entire length, and the overall length is formed to be longer than at least the entire width dimension of the flanges 62 on both the left and right sides of the shape steel 61. The steel 61 is disposed on the lower surface side of the flange 62.

次に、一対の挟持体は、図１において棒状体２の左側に取付けられた第１挟持体１１と、棒状体２の右側に取付けられた第２挟持体２１とで構成されている。第１挟持体１１は、左右対称形状の鋼板がその中央で１８０度折り返されて断面略Ｕ字状に形成され、一対の側壁１２が間隔をおいて対向している。第１挟持体１１の中央の折り返し部１３は棒状体２の外径より僅かに大きい内径に形成され、この折り返し部１３の内部は貫通部１４として棒状体２が貫通するようになっている。両側壁１２は形鋼６１のフランジ６２の先端部と対向する側部に挿入開口１５を有する切欠空間１６が形成されており、切欠空間１６の奥部に形鋼６１のフランジ６２の先端部が当接するようになっている。 Next, the pair of sandwiching bodies includes a first sandwiching body 11 attached to the left side of the rod-like body 2 in FIG. 1 and a second sandwiching body 21 attached to the right side of the rod-like body 2. The first sandwiching body 11 has a symmetrical steel plate folded back by 180 degrees at the center and formed in a substantially U-shaped cross section, and a pair of side walls 12 are opposed to each other with a gap. The folded portion 13 at the center of the first sandwiching body 11 is formed to have an inner diameter slightly larger than the outer diameter of the rod-shaped body 2, and the rod-shaped body 2 penetrates inside the folded portion 13 as a through portion 14. The both side walls 12 are formed with a notch space 16 having an insertion opening 15 on the side facing the tip of the flange 62 of the shape steel 61, and the tip of the flange 62 of the shape steel 61 is located at the back of the notch space 16. It comes to contact.

更に、第１挟持体１１の両側壁１２における挿入開口１５と反対側の側縁部１７には段部状に切欠された係合部１８が形成されており、その係合部１８は、図１及び図４(b)に示すように、棒状体２において第１挟持体１１側に螺合するダブルナットからなる第１ナット３の周壁３ａが係合し、第１ナット３が回動するのを防止している。具体的には、図３に示す寸法に形成されており、第１挟持体１１の対向する側壁１２間の内寸Ｌ１は第１ナット３の対辺の間隔Ｌ２より小さく形成されている。したがって、棒状体２の軸心Ｏを中心とする、第１ナット３の辺と第１挟持体１１の側壁１２の端面角部とが当接する当接点Ｐ１までの半径Ｒ１は、棒状体２の軸心Ｏを中心とする、第１ナット３の頂点Ｐ２までの半径Ｒ２より小さい。このため、第１ナット３が棒状体２の軸心Ｏを中心に回動しようとしても第１ナット３の周壁３ａが第１挟持体１１の側壁１２の端面角部と当接し干渉するから、第１ナット３の回動は阻止される。加えて、係合部１８はワッシャー５が面当接する形態で切欠内に嵌入するようになっているとともに、切欠の深さは少なくともワッシャー５の厚さより小さく形成され、ワッシャー５の片側表面が側壁１２の左側の側縁部１７の端面１７ａと面一または僅かに外側に突出する大きさに形成されている。 Furthermore, an engaging portion 18 that is notched in a step shape is formed on the side edge portion 17 on the opposite side of the insertion opening 15 in the both side walls 12 of the first sandwiching body 11. As shown in FIG. 1 and FIG. 4 (b), the peripheral wall 3a of the first nut 3 made of a double nut screwed to the first sandwiching body 11 side in the rod-like body 2 is engaged, and the first nut 3 rotates. Is preventing. Specifically, the inner dimension L1 between the opposing side walls 12 of the first holding body 11 is smaller than the distance L2 between the opposite sides of the first nut 3. Therefore, the radius R1 up to the contact point P1 where the side of the first nut 3 and the end surface corner of the side wall 12 of the first sandwiching body 11 come into contact with each other about the axis O of the rod-shaped body 2 is It is smaller than the radius R2 from the center O to the vertex P2 of the first nut 3. For this reason, even if the first nut 3 tries to rotate around the axis O of the rod-shaped body 2, the peripheral wall 3 a of the first nut 3 comes into contact with and interferes with the end face corner of the side wall 12 of the first holding body 11.

次に、上記のように構成された固定具１を形鋼６１のフランジ６２に固定し、配設体を支持する方法を説明する。
最初に、支持本体４４と連結体４５とを取着ボルト４６及びナット４７を介して組付けて支持部材４１となし、これを連結ボルト４２及びナット４３を介して金具３１に連結する。次いで、支持部材４１が連結された金具３１の挿入開口３７ａから切欠空間３７内に形鋼６１の右側のフランジ６２を挿入し、そのフランジ６２の先端を金具３１の切欠空間３７の奥部に当接させ、固定ボルト３２を締付けて金具３１の当接フランジ３８とで形鋼６１のフランジ６２を挟持し、これにより金具３１を形鋼６１のフランジ６２に固定する。次に、棒状体２を金具３１に横方向に架設した架設ボルト３４の下方に位置するようにして金具３１内に挿通し、更に第１挟持体１１の貫通部１４及び第２挟持体２１の挟持部２２の貫通部２４に貫通させて形鋼６１のフランジ６２の下側に配置する。そして、この状態で、第１挟持体１１の外側即ち左側から棒状体２にダブルナットからなる第１ナット３を螺合させるとともに、第２挟持体２１の外側即ち右側から棒状体２にワッシャー５、ばね座金６、第２ナット４の順でこれらを取付けて、固定具１を仮組付状態とする。 Next, a method for fixing the fixture 1 configured as described above to the flange 62 of the shaped steel 61 and supporting the arrangement body will be described.
First, the support main body 44 and the connecting body 45 are assembled via the attachment bolt 46 and the nut 47 to form the support member 41, and this is connected to the metal fitting 31 via the connection bolt 42 and the nut 43. Next, the right flange 62 of the shape steel 61 is inserted into the notch space 37 from the insertion opening 37 a of the metal fitting 31 to which the support member 41 is connected, and the tip of the flange 62 is brought into contact with the inner part of the notch space 37 of the metal fitting 31. Then, the fixing bolt 32 is tightened, and the flange 62 of the section steel 61 is clamped by the abutting flange 38 of the metal fitting 31, whereby the metal fitting 31 is fixed to the flange 62 of the shape steel 61. Next, the rod-shaped body 2 is inserted into the metal fitting 31 so as to be positioned below the erection bolt 34 installed in the horizontal direction on the metal fitting 31, and further, the penetration portion 14 of the first holding body 11 and the second holding body 21 It penetrates the penetration part 24 of the clamping part 22 and is arranged below the flange 62 of the shaped steel 61. In this state, the first nut 3 made of a double nut is screwed to the rod-like body 2 from the outside, that is, the left side of the first sandwiching body 11, and the washer 5 is attached to the rod-like body 2 from the outside, that is, the right side of the second sandwiching body 21. Then, the spring washer 6 and the second nut 4 are attached in this order, and the fixture 1 is temporarily assembled.

次に、この状態で、第１挟持体１１を形鋼６１の左側のフランジ６２に取付け、第１挟持体１１の挿入開口１５からこの左側のフランジ６２を切欠空間１６内に挿入し、このフランジ６２の先端を第１挟持体１１の切欠空間１６の奥部に当接させる。このとき、ダブルナットからなる第１ナット３は、図４(a)に示す状態から第１挟持体１１を第１ナット３側に移動させるなどして、図４(b)に示すように、周壁３ａを第１挟持体１１の係合部１８に係合させておく。続いて、第２挟持体２１の挟持部２２を右側方から金具３１の一対の側壁３３内に挿入し、金具３１の両側壁３３間に架設された架設ボルト３４のねじ部を挟持部２２の挿入開口２６から切欠空間２７内に挿入し、架設ボルト３４のねじ部を切欠空間２７の奥部に当接させる。これにより固定具１を形鋼６１のフランジ６２に取付けたら、第２ナット４の締付けを開始する。第２ナット４の締付けにおいては、ワッシャー５を図５(a)の状態から図５(b)に示すように挟持部２２の係合部２９内に嵌入させる。すると、ワッシャー５の片側表面は側壁２５の右端の側縁部２８の端面２８ａと面一または僅かに外側に突出するので、第２ナット４はその周壁４ａが第２挟持体２１の係合部２９に係合することなく回動可能な状態となる。そこで、図５(c)に示すように、第２ナット４を回す。このようにして第２ナット４を回してその締付けが完了すると、一対の挟持体は両側のナットにより締付けられて形鋼６１のフランジ６２を両側方から強く挟持する。その結果、金具３１が形鋼６１のフランジ６２から側方に外れるのが確実に防止される。なお、第２ナット４側に取付けたばね座金６は必ずしも要するものではない。 Next, in this state, the first clamping body 11 is attached to the left flange 62 of the shape steel 61, and the left flange 62 is inserted into the notch space 16 from the insertion opening 15 of the first clamping body 11. The front end of 62 is brought into contact with the inner part of the notch space 16 of the first holding body 11. At this time, the first nut 3 formed of a double nut is moved from the state shown in FIG. 4A to the first nut 3 side, as shown in FIG. The peripheral wall 3 a is engaged with the engaging portion 18 of the first holding body 11. Subsequently, the sandwiching portion 22 of the second sandwiching body 21 is inserted into the pair of side walls 33 of the metal fitting 31 from the right side, and the screw portion of the installation bolt 34 installed between the side walls 33 of the metal fitting 31 is inserted into the holding portion 22. The insertion opening 26 is inserted into the cutout space 27, and the threaded portion of the installation bolt 34 is brought into contact with the back of the cutout space 27. Thus, when the fixture 1 is attached to the flange 62 of the shaped steel 61, tightening of the second nut 4 is started. In tightening the second nut 4, the washer 5 is fitted into the engaging portion 29 of the clamping portion 22 from the state of FIG. 5A as shown in FIG. Then, the one side surface of the washer 5 protrudes flush with or slightly outward from the end surface 28 a of the side edge 28 at the right end of the side wall 25, so that the peripheral wall 4 a of the second nut 4 is an engaging portion of the second clamping body 21. It becomes a state which can be rotated without engaging 29. Therefore, as shown in FIG. 5 (c), the second nut 4 is turned. When the second nut 4 is turned and thus tightened, the pair of sandwiching bodies are fastened by the nuts on both sides to strongly clamp the flange 62 of the shaped steel 61 from both sides. As a result, the metal fitting 31 is reliably prevented from coming off from the flange 62 of the section steel 61 laterally. The spring washer 6 attached to the second nut 4 side is not necessarily required.

その後、配設体を支持させる支持ボルトを第２挟持体２１の支持部材４１の支持本体４４に形成された切欠帯溝４８ａに挿通し、配設体を支持部材４１に支持させる。図８に、配設体として蛍光灯７１を支持した固定具１を示す。なお、支持部材４１の連結体４５に対して支持本体４４の取着向きを反転することにより、蛍光灯７１を形鋼６１の中央部で支持させることもできる。以上により、形鋼６１のフランジ６２への固定具１の固定及び配設体としての蛍光灯７１の支持が完了する。 Thereafter, the support bolt for supporting the arrangement body is inserted into the notch band groove 48 a formed in the support main body 44 of the support member 41 of the second holding body 21, and the arrangement body is supported by the support member 41. FIG. 8 shows the fixture 1 that supports a fluorescent lamp 71 as an arrangement body. Note that the fluorescent lamp 71 can be supported at the center of the section steel 61 by reversing the mounting direction of the support body 44 with respect to the connecting body 45 of the support member 41. The fixing of the fixture 1 to the flange 62 of the shape steel 61 and the support of the fluorescent lamp 71 as the arrangement body are thus completed.

ところで、上記実施形態においては、第１ナット３を第１挟持体１１の係合部１８に係合させてその回動を防止する一方、第２挟持体２１の係合部２９にワッシャー５を介在させることにより第２ナット４の回動を許容し、第２挟持体２１側から締付作業を行なっているが、第２挟持体２１側の周辺に障害物等があって周辺スペースが小さい場合には、第１挟持体１１側から締付作業を行なうこともできる。その場合は、第２挟持体２１の係合部２９にはワッシャー５を介在させることなく第２ナット４が係合する回動防止状態とし、その一方、第１挟持体１１の係合部１８にはワッシャー５を介在させて第１ナット３が回動する回動許容状態とすればよい。なお、この場合、締付側の第１ナット３は単一のナットとし、保持側の第２ナット４は単一のナットまたはダブルナットとする。 By the way, in the said embodiment, while engaging the 1st nut 3 with the engaging part 18 of the 1st clamping body 11 and preventing the rotation, the washer 5 is attached to the engaging part 29 of the 2nd clamping body 21. FIG. The second nut 4 is allowed to rotate by being interposed, and tightening work is performed from the second clamping body 21 side, but there are obstacles around the second clamping body 21 side, and the surrounding space is small. In this case, the tightening operation can be performed from the first holding body 11 side. In that case, the engaging part 29 of the second clamping body 21 is in a rotation-preventing state in which the second nut 4 is engaged without the washer 5 interposed, while the engaging part 18 of the first clamping body 11 is engaged. In this case, it is sufficient that the first nut 3 is allowed to rotate with the washer 5 interposed. In this case, the first nut 3 on the tightening side is a single nut, and the second nut 4 on the holding side is a single nut or a double nut.

次に、上記のように構成された本実施形態の固定具１の作用を説明する。
固定具１は、第１挟持体１１に、第１ナット３の周壁３ａに当接し係合して第１ナット３が回動するのを防止する係合部１８を備えているので、第２挟持体２１において第２ナット４を締付けて一対の挟持体で形鋼６１のフランジ６２を挟持する際、第１ナット３がから回りして締付困難となるのを防止するために、反対側に離間している第１ナット３に手を伸ばしてこれを保持する必要がない。一方、第２挟持体２１の係合部２９にはワッシャー５が嵌入し、これが係合部２９を形成する切欠空間を充填するスペーサとして機能するので、第２ナット４は第２挟持体２１の係合部２９に係合することなく回転し、第２挟持体２１の挟持部２２の右側の側縁部２８を押圧する。これにより、第２挟持体２１側において第１挟持体１１の第１ナット３を片手で保持することなく第２挟持体２１の第２ナット４を回すだけの操作で、左右一対の挟持体を両側から締付け、これら一対の挟持体で形鋼６１のフランジ６２を挟持することができる。したがって、形鋼６１のフランジ６２に対する固定具１の固定作業を楽に行なうことができる。 Next, the operation of the fixture 1 of the present embodiment configured as described above will be described.
Since the fixture 1 includes the engaging portion 18 that contacts the first clamping body 11 and engages with the peripheral wall 3a of the first nut 3 to prevent the first nut 3 from rotating. When the second nut 4 is clamped in the clamping body 21 and the flange 62 of the shaped steel 61 is clamped by the pair of clamping bodies, the first nut 3 is turned around to prevent it from becoming difficult to tighten. There is no need to reach and hold the first nut 3 which is spaced apart. On the other hand, the washer 5 is fitted into the engaging portion 29 of the second sandwiching body 21, and this functions as a spacer that fills the notch space forming the engaging portion 29, so that the second nut 4 is attached to the second sandwiching body 21. It rotates without engaging with the engaging portion 29 and presses the right side edge portion 28 of the holding portion 22 of the second holding body 21. As a result, the pair of left and right clamping bodies can be moved by simply turning the second nut 4 of the second clamping body 21 without holding the first nut 3 of the first clamping body 11 with one hand on the second clamping body 21 side. The flange 62 of the shaped steel 61 can be clamped by clamping from both sides. Therefore, the fixing work of the fixing tool 1 to the flange 62 of the shape steel 61 can be easily performed.

加えて、特に、これらの係合部はワッシャー５を介在させると、それがスペーサとして機能し、ナットの周壁は係合部から離脱して係合が解除されるから、これらの係合部にワッシャー５を介在させるか否かにより回動防止状態または回動許容状態とすることができる。そして、棒状体２の左右いずれの方向からでも、反対側のナットを保持することなく手前側のナットの締付作業のみで形鋼６１のフランジ６２に固定具１を固定することができる。したがって、第１挟持体１１及び第２挟持体２１のそれぞれについて、側壁に切欠形成した係合部を設けたものとこれを設けてないものとの２種類を用意する必要はなく、第１挟持体１１及び第２挟持体２１はいずれも、係合部を設けた１種類のみを用意すれば足りる。しかも、挟持体の共通化を、側壁に切欠形成した係合部にワッシャー５を介在させるか否かという極く簡易な構成で簡単かつ安価に実現することができる。なお、第１挟持体１１と第２挟持体２１との間においても共通化すれば、固定具１全体で１種類の挟持体のみを用いて形鋼６１のフランジ６２への固定を行なうことができる。 In addition, in particular, when the washer 5 is interposed between these engaging portions, it functions as a spacer, and the peripheral wall of the nut is detached from the engaging portion and the engagement is released. Depending on whether or not the washer 5 is interposed, the rotation prevention state or the rotation permission state can be achieved. And the fixing tool 1 can be fixed to the flange 62 of the shape steel 61 only from the right and left directions of the rod-shaped body 2 by only tightening the nut on the near side without holding the nut on the opposite side. Therefore, it is not necessary to prepare two types of the first sandwiching body 11 and the second sandwiching body 21, that is, the one provided with the engagement portion formed in the side wall and the one not provided with this. For the body 11 and the second sandwiching body 21, it is sufficient to prepare only one type provided with an engaging portion. In addition, it is possible to easily and inexpensively realize the common use of the sandwiching body with an extremely simple configuration of whether or not the washer 5 is interposed in the engaging portion formed in the side wall. In addition, if it also makes common between the 1st clamping body 11 and the 2nd clamping body 21, it will fix to the flange 62 of the structural steel 61 using only one type of clamping body by the fixing tool 1 whole. it can.

更に、第２挟持体２１は支持部材４１を備えているから、各種配設体を支持できる。
また、第２挟持体２１の固定部は、側面視コ字状に形成された金具３１で形成され、固定ボルト３２を備えているから、形鋼６１のフランジ６２への固定を簡単に行なうことができる。
加えて、第１ナット３は、ダブルナットで形成されているから、これを強固に棒状体２に保持させることができる。 Furthermore, since the 2nd clamping body 21 is provided with the supporting member 41, it can support various arrangement | positioning bodies.
Moreover, since the fixing part of the second clamping body 21 is formed by a metal fitting 31 formed in a U shape in a side view and includes a fixing bolt 32, the shape steel 61 can be easily fixed to the flange 62. Can do.
In addition, since the first nut 3 is formed of a double nut, it can be firmly held by the rod-shaped body 2.

ところで、上記実施形態においては、棒状体２において第１挟持体１１側に第１ナット３を螺合し、第２挟持体２１側に第２ナット４を螺合して、左右のナットにより一対の挟持体を形鋼６１のフランジ６２に挟持させているが、図９に示すように、長尺のねじ部を有する六角ボルトで形成することもできる。即ち、図９に示す固定具１は、左方向から六角ボルト７のねじ部を第１挟持体１１の貫通部１４に貫通し、次いで、第２挟持体２１の挟持部２２の貫通部２４に貫通した後、これを貫通した六角ボルト７のねじ部の先端側にワッシャー５及びばね座金６を外挿し、第２ナット４を螺合してなる。ここで、六角ボルト７は請求項のボルト体に相当し、六角ボルト７の頭部は請求項のボルト体の頭部に相当する。なお、ボルト体は、六角ボルト７に限られず、他の多角ボルト等を用いてもよい。 By the way, in the said embodiment, the 1st nut 3 is screwed in the 1st clamping body 11 side in the rod-shaped body 2, and the 2nd nut 4 is screwed in the 2nd clamping body 21 side, and it is a pair by left and right nuts. However, as shown in FIG. 9, it can also be formed by a hexagon bolt having a long threaded portion. That is, the fixture 1 shown in FIG. 9 penetrates the threaded portion of the hexagon bolt 7 from the left direction to the penetrating portion 14 of the first sandwiching body 11 and then the penetrating portion 24 of the sandwiching portion 22 of the second sandwiching body 21. After penetrating, the washer 5 and the spring washer 6 are extrapolated to the front end side of the threaded portion of the hexagon bolt 7 penetrating the second nut 4 and screwed into the second nut 4. Here, the hexagon bolt 7 corresponds to the bolt body of the claims, and the head of the hexagon bolt 7 corresponds to the head of the bolt body of the claims. The bolt body is not limited to the hexagon bolt 7 and other polygonal bolts or the like may be used.

この固定具１においては、六角ボルト７の頭部が第１挟持体１１の係合部１８に係合し、六角ボルト７が回動するのが防止されるとともに、第２挟持体２１の係合部２９にはワッシャー５が嵌入して第２ナット４が回動可能となっている。したがって、この固定具１においても、図１乃至図８に示す固定具１と同様に、第２挟持体２１側において、六角ボルト７の頭部に手を伸ばしてこの頭部を保持することなく、第２挟持体２１の第２ナット４を回すだけの操作で、左右一対の挟持体を両側から締付け、これら一対の挟持体で形鋼６１のフランジ６２を挟持することができる。なお、六角ボルト７は左右を逆に配置し、図９の右方向から六角ボルト７のねじ部を第２挟持体２１の挟持部２２の貫通部２４に貫通し、次いで、第１挟持体１１の貫通部１４に貫通した後、これを貫通した六角ボルト７のねじ部の先端側にワッシャー５及びばね座金６を外挿し、１個のナットからなる第１ナットを螺合させてもよい。 In this fixture 1, the head of the hexagon bolt 7 is engaged with the engaging portion 18 of the first holding body 11, and the hexagon bolt 7 is prevented from rotating and the engagement of the second holding body 21. The washer 5 is fitted in the joint portion 29 so that the second nut 4 can be rotated. Therefore, also in this fixture 1, as in the fixture 1 shown in FIGS. 1 to 8, on the second clamping body 21 side, without extending the hand to the head of the hexagon bolt 7 and holding this head. By simply turning the second nut 4 of the second clamping body 21, the pair of left and right clamping bodies can be tightened from both sides, and the flange 62 of the shaped steel 61 can be clamped by these pair of clamping bodies. The hexagon bolts 7 are arranged on the left and right sides, and the threaded portion of the hexagon bolt 7 is penetrated from the right direction of FIG. 9 into the through portion 24 of the holding portion 22 of the second holding body 21, and then the first holding body 11. After passing through the through portion 14, the washer 5 and the spring washer 6 may be extrapolated to the tip side of the threaded portion of the hexagon bolt 7 that has passed through the through portion 14, and a first nut made of one nut may be screwed together.

次に、本発明の別の実施形態の固定具１を図１０及び図１１に基づいて説明する。なお、図１０(b)では便宜上、金具３１の手前側の側壁３３の記載は省略してある。
図１０において、固定具５１はＬ形状の形鋼６３のフランジ６４に固定されて配設体を支持するものであり、形鋼６３のフランジ６４を挟持する一対の挟持体である第１挟持体５２及び第２挟持体５３と、両端の周辺部の外面に雄ねじを備え、Ｌ字状に屈曲された棒状体５４と、各挟持体の外側から棒状体５４に螺合するナット５５とを備えている。第１挟持体５２は、図１乃至図９に示した実施形態の第２挟持体２１の挟持部２２と同一に形成されており、前記ナット５５に係合してこのナット５５の回動を防止するとともにワッシャー５が介在することによりこのナット５５が係合することなく回動が可能となる係合部５６を備えている。また、第２挟持体５３は、図１乃至図９に示した実施形態の第２挟持体２１と同一に形成されており、同様に、係合部５７を備えている。このように形成された一対の挟持体の係合部には、いずれもワッシャー５が介在し、ナット５５が回動可能となっている。前記棒状体５４は両端部がそれぞれ形鋼６３のフランジ６４の先端部より少なくともナット５５が螺合し得る分だけ外方に突出する長さに形成されている。 Next, a fixture 1 according to another embodiment of the present invention will be described with reference to FIGS. 10 and 11. In FIG. 10B, the illustration of the side wall 33 on the front side of the metal fitting 31 is omitted for convenience.
In FIG. 10, the fixture 51 is fixed to a flange 64 of an L-shaped section steel 63 to support the arrangement body, and is a first sandwich body that is a pair of sandwich bodies that sandwich the flange 64 of the section steel 63. 52 and a second sandwiching body 53, a rod-shaped body 54 having external threads on the outer surfaces of the peripheral portions at both ends, bent in an L shape, and a nut 55 screwed into the rod-shaped body 54 from the outside of each sandwiching body. ing. The first clamping body 52 is formed in the same manner as the clamping portion 22 of the second clamping body 21 of the embodiment shown in FIGS. 1 to 9, and engages with the nut 55 to rotate the nut 55. An engaging portion 56 is provided that prevents the nut 55 from being engaged and prevents the nut 55 from engaging with the washer 5. Moreover, the 2nd clamping body 53 is formed the same as the 2nd clamping body 21 of embodiment shown in FIG. 1 thru | or FIG. 9, and is provided with the engaging part 57 similarly. A washer 5 is interposed between the engaging portions of the pair of sandwiching bodies formed as described above, and the nut 55 is rotatable. The rod-like body 54 is formed such that both ends protrude outward from the tip end of the flange 64 of the shaped steel 63 by at least the amount that the nut 55 can be screwed.

この固定具５１は、ナット５５を回して締付けることにより、第１挟持体５２と棒状体５４の水平部とで形鋼６３の上下方向のフランジ６４を挟持し、第２挟持体５３の挟持部２２と棒状体５４の垂直部とで形鋼６３の水平方向のフランジ６４を挟持しており、これにより固定具５１を形鋼６３のフランジ６４に固定している。したがって、本実施形態においては、両側のナット５５とも各挟持体の係合部にワッシャー５を介在させて回動可能な状態としている。ここで、Ｌ形状の形鋼６３のフランジ６４を挟持する第１挟持体５２及び第２挟持体５３は２個のナット５５がいずれも回動可能な状態とする必要があるから、挟持体に、ナット５５を係合させてその回動を防止する係合部は特に設ける必要はない。しかし、建物に、Ｈ形状の形鋼６１とＬ形状の形鋼６３とが構築されている場合などにおいては、各挟持体を共通化できれば、複数種類の挟持体を用意し、使い分ける煩わしさがなくなり、運搬、保管管理も楽になるので都合がよい。そこで、図１０に示す固定具５１では、それぞれに係合部を設けた一対の挟持体を使用しているのである。 The fixing member 51 is configured to clamp the flange 64 in the vertical direction of the shape steel 63 between the first sandwiching body 52 and the horizontal portion of the rod-shaped body 54 by turning and tightening the nut 55, and the sandwiching portion of the second sandwiching body 53. 22 and the vertical portion of the rod-shaped body 54 sandwich a horizontal flange 64 of the section steel 63, thereby fixing the fixture 51 to the flange 64 of the section steel 63. Therefore, in this embodiment, the nuts 55 on both sides are rotatable with the washers 5 interposed between the engaging portions of the holding members. Here, since it is necessary for both the 1st clamping body 52 and the 2nd clamping body 53 which clamp the flange 64 of the L-shaped shaped steel 63 to be the state which can rotate two nuts 55, it is set as a clamping body. The engaging portion that engages the nut 55 to prevent its rotation is not particularly required. However, in the case where an H-shaped section 61 and an L-shaped section 63 are constructed in a building, if each sandwiched body can be shared, a plurality of types of sandwiched bodies are prepared and bothersome to use properly. It is convenient because it is easy to carry and store. Therefore, in the fixture 51 shown in FIG. 10, a pair of sandwiching bodies each provided with an engaging portion is used.

図１１に、固定具５１の第２挟持体５３の支持部材４１に配設体として吊りボルト７２を支持させた例を示す。図１１において、吊りボルト７２はこれに螺合した上下一対のナット７３で支持本体４４の支持板部４８を挟持することにより第２挟持体５３の支持部材４１に垂設されている。なお、吊りボルト７２は、金具３１に対して支持部材４１を連結ボルト４２の軸心を中心に上下方向に所定角度回動させた後、締付けて固定することにより、傾斜した状態で吊り下げることもできる。 FIG. 11 shows an example in which a suspension bolt 72 is supported as an arrangement body on the support member 41 of the second clamping body 53 of the fixture 51. In FIG. 11, the suspension bolt 72 is suspended from the support member 41 of the second sandwiching body 53 by sandwiching the support plate portion 48 of the support body 44 with a pair of upper and lower nuts 73 screwed into the suspension bolt 72.
